Turbidity Meters

TN100-IR Portable Turbidimeter (waterproof)

The microprocessor-based waterproof TN100 meter is an easy-to-use turbidimeter that meets the rigour of rugged field applications. It is a “must -have” for anyone monitoring turbidity on the go.

Using an Infrared light source, it delivers laboratory accuracy with a resolution of 0.01 NTU across an extended range of up to 20 NTU (Nephelometric Turbidity Units).

Details:

  • IP67 Waterproof and Dustproof – Cleaning and maintenance is simple. It floats!
  • Automatic Push-Button Calibration (4 points) for unprecedented full-range accuracy
  • Sturdy Carrying Kit complete with 4 calibration standards, 3 empty cuvettes, batteries and comprehensive instruction manual
  • Power-saving feature allows over 1200 measurements to be taken with a single set of AAA alkaline batteries
  • Large Easy-to-Read Display for optimum viewing of measurements with user-friendly message codes for easy troubleshooting
  • Meets Performance Criteria as specified by ISO 1727 (DIN EN 27027) method

TN400 Portable Turbidity Meter Kit

 

The Apera Instruments TN400 Portable Turbidity Meter, Large Colored TFT display with graphic and text guides, Accuracy: ±1% or 0.02 NTU, whichever is greater

  • Infrared light source — ISO7027 compliant
  • Easy and quick calibration
  • TFT Colored Screen (measurement mode, green in calibration) with graphic and text operation guides
  • U.S. EPA certified, non-toxic, easy-to-use polymer standard solutions
  • CE certified and comes with 2-Year Warranty

The Apera Instruments TN400 Portable Turbidity Meter is built with an infrared light source, using ISO7207 compliant nephelometric method (90°), equipped with a large TFT colored screen, designed for reliable turbidity measurements from 0 to 1000 NTU in various applications both in-field and in-lab e.g. environmental monitoring, water treatment, beverage making, etc.

The test kit comes with 4 vials of high-molecular polymer turbidity standard solutions (0.02 NTU, 20.0 NTU, 100 NTU, 800 NTU), an EPA approved primary standard for calibration of turbidity sensors that is safe, non-toxic and disposable. It is NIST traceable to particle size/distribution and optical density, and its inherent stability means it does not settle from suspension.

The standards have a guaranteed one-year shelf life even if you’ve opened the bottle and happened not to have recapped it tightly. The convenient submicron polymer suspensions are non-toxic primary calibration standards approved by the US EPA for drinking water analysis for turbidity.

The meter is CE certified and comes with a 2-year warranty.
